Induced Size-Ramsey Numbers of Odd Cycles via Spread Measures

Lanchao Wang, Xiaolin Wang

We prove that, for every $k \geq 2$ and every sufficiently large odd $n$ , the induced size--Ramsey number of $C_{n}$ satisfies \[ \widehat R_{\mathrm{ind}}(C_n;k)=e^{Θ(k)}n. \] This imp…

The Multicolour Size--Ramsey Number of an Even Cycle

Lanchao Wang, Xiaolin Wang

We determine the $k$ -colour size--Ramsey number of even cycles up to absolute constant factors. For every $k \geq 2$ and every even $n \geq 100 lo g k$ , \[ \widehat R_k(C_n)=Θ(k^2\log k)n…
